FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

Part 8: Transmission of ITU-R BT.601 style digital video data
1
Scope
This part of IEC 61883 specifies a protocol for the transport of uncompressed or compressed
video data in the 4:2:2 format of recommendation ITU-R BT.601 (including compatible
extensions to this format for the higher and lower resolutions of other commonly used video
resolutions) over high performance serial bus, as specified by IEEE Std 1394-1995 as
amended by IEEE Std 1394a-2000 and IEEE Std 1394b-2002 (collectively IEEE 1394). The
data formats for the encapsulation of video data are compatible with those specified by
IEC 61883-1. Associated audio data, if any, should be formatted as specified by IEC 61883-6.
There are many commonly used video formats unsupported by IEC 61883, such as MPEG-4,
Windows Media Format (WMF) and the format used by automotive navigation applications.
Support for all or most of these formats in rendering devices would require implementation of
multiple video codecs. This is an undue burden that may be avoided if the source device
converts to ITU-R BT.601 4:2:2 format and, if necessary, compresses the data with a codec
supported by all destination devices. An additional advantage is that on-screen display (OSD)
information may be mixed with video data prior to transmission to the rendering device.
Because ITU-R BT.601 4:2:2 format is widely used internally in contemporary AV equipment,
this specification permits straight-forward integration of IEEE 1394 into these devices and
enables markets whose usage scenarios include single video sources transmitting to one or
more video displays, such as:
–
consumer electronic STB or DVD video rendered by multiple displays in the home;
–
automotive navigation and entertainment; and
–
aeronautical in-flight entertainment.
For the sake of interoperability and bounded implementation complexity, it is essential that
the specification provide the following:
2
–
a 1394 TA controlled list of compression codecs; and
–
at a minimum, a reference to one video compression codec.

3.2.1
Notation
Numeric values
Decimal and hexadecimal are used within this standard. By editorial convention, decimal
numbers are most frequently used to represent quantities or counts. Addresses are uniformly
represented by hexadecimal numbers. Hexadecimal numbers are also used when the value
represented has an underlying structure that is more apparent in a hexadecimal format than in
a decimal format.
Decimal numbers are represented by Arabic numerals without subscripts or by their English
names. Hexadecimal numbers are represented by digits from the character set 0 – 9 and A - F
followed by the subscript 16. When the subscript is unnecessary to disambiguate the base of
the number it may be omitted. For the sake of legibility hexadecimal numbers are separated
into groups of four digits separated by spaces.
As an example, 42 and 2A 16 both represent the same numeric value.
3.2.2
Bit, byte and quadlet ordering
This specification uses the facilities of Serial Bus, IEEE 1394, and therefore uses the ordering
conventions of Serial Bus in the representation of data structures. In order to promote
interoperability with memory buses that may have different ordering conventions, this
specification defines the order and significance of bits within bytes, bytes within quadlets and
quadlets within octlets in terms of their relative position and not their physically addressed
position.
Within a byte, the most significant bit, msb, is that which is transmitted first and the least
significant bit, lsb, is that which is transmitted last on serial bus, as illustrated below. The

When block transfers take place that are not quadlet aligned or not an integral number of
quadlets, no assumptions can be made about the ordering (significance within a quadlet) of
bytes at the unaligned beginning or fractional quadlet end of such a block transfer, unless an
application has knowledge (outside of the scope of this specification) of the ordering
conventions of the other bus.

4.1
Reference model for data transmission
Model overview
The presently defined compression standards for IEEE 1394 transport, DV and MPEG2, have
difficulties at the system level in a practical consumer AV network. Both offer excessive
compression for simple transport over a wide bandwidth network and carry the associated
complexity of coding and decoding signals. Each are fine for their intended purpose, but have
excessive cost for simple video transport. Conventional video equipment is interfaced with
analog cables carrying a number of signal formats, and it is this low cost and universal
connection capability which digital interfaces need to emulate. Thus the analog output from
any DVD player will connect to any TV, and this is seen as adequate by equipment
manufacturers. Digital interfaces would allow many additional features, but providing every
input with the capability of decoding both DV and MPEG2 in all available standards and
resolutions is unnecessarily expensive. Inside equipment variations on the broadcast
equipment ITU-R BT.601-5/BT.656-4 interface are common and provide a universal interface
standard for digital video transport. The coding system in ITU-R BT.601-5 sends YUV data
across an 8 bit interface between integrated circuits, for example an MPEG decoder and DAC.
If the decoder and DAC are separated by 1394 in their separate boxes there will be a
reduction in cost at the source device and the sink device will be independent from the video
encoding mechanism.
This standard describes the method of passing YUV video signals across IEEE 1394 based
upon the formats defined by ITU-R BT.601-5. Familiarity with the specifications ITU-R BT.6015, ITU-R BT.656-4 and IEC 61883 is necessary to follow the technical details.
There is also the capability to transfer data in YUV 4:4:4 and 24 bit RGB formats. This allows
video to be transferred without the need for color space sub-sampling.
It is valid to transmit all video modes as uncompressed data as long as the IEEE 1394 bus
bandwidth is available. In practice some video modes will not be transportable in an
uncompressed state.

This model also allows for the future development of video codecs. Since the transport of the
video data is independent of the original source encoding as new codecs are deployed, such
as MPEG-4, the transport mechanism described in this document will not need to change.
4.2
Compression
To allow the transport of high definition video signals at bus speeds less than S1600 or to
allow the transport of multiple video streams it is essential that the video stream is
compressed. This compression need not be more than about 10:1 and should have minimal
discernable impact on the displayed image. Since compression is required to transport some
of the video modes it is necessary to reference at least one compression codec in this
specification. A suitable video compression codec is referenced for this purpose in Table 2.
There is no requirement that a source or sink device implement this codec. Other suitable
video compression codecs may be added in the future.
4.3
Isochronous packet header

The tag field shall be set to 1 16 indicating that the packet has the Common Isochronous

described in 4.4.
The definition of the remaining fields is outside of the scope of this specification.

SID denotes the source node ID. This is bus configuration dependent.
–
DBS value depends upon the video mode being transported and the color space used.
This value is dependent upon the compression mode, color space and video mode.
The DBS value for compression mode 0 16 can be calculated from the source packet
size given in Table 1 by dividing the value by 4. For other compression modes refer to
the documention available from the codec vendor.
–
FN shall always have a value of 016 . There shall only be 1 data block per source
packet.
–
QPC shall always have a value of 0 16 . There shall be no padding.
–
SPH shall be 0 16 . The source packet header is not present.
–
Since FN is 0 16 the value of DBC shall always increment by the number of source
packets present in the Isochronous packet. This field indicates the count value of the
first data block in the current isochronous packet.

The ND field is used to signify whether the data payload of the isochronous packet after the
CIP header is valid. If ND is set to 1 2 it indicates that the data is not valid and shall be
ignored, this setting is only used in blocking transmission mode (see 4.7.1.3). The DBC field
in the CIP header of a packet which has ND set to 1 2 shall be the count value of the next valid
data block. The transmission of an isochronous packet with this bit set shall not cause the
value of DBC to increment. If ND is set to 02 it indicates that the data payload of the
isochronous packet after the CIP header is valid. In non-blocking transmission mode, see
4.7.1.2, ND shall be set to 0 2 for all isochronous packets.
4.5
Stream definition
A stream that conforms to this specification is governed by three key parameters:
–
video mode, see Table 1 below. Additional information for each video mode is given in
Annex B.
–
compression mode, see Table 2 below.
–
color space, see Table 3 below.
Each of these parameters includes an unconstrained mode that allows modes not explicitly
defined to be transmitted. The use of these unconstrained modes is beyond the scope of this
standard. However, it is expected that their use will be determined by negotiation before
transmission.
For transmission of compression mode 0 16 data the packetization and timing characteristics
are defined in this specification.
For transmission of compression mode 1 16 and 2 16 data the packetization and timing
characteristics are defined in the applicable specification document referenced in Table 2.

Source packet format
For a stream that conforms to this specification each IEEE-1394 isochronous packet consists
of the CIP header followed by zero or more source packets. The general format of the source
packet for all compression modes and all source packet types is shown in Figure 7 below. It
contains a single quadlet of type specific information followed by data. The size of each
source packet is compression mode, video mode and color space mode dependent. The
permitted video, compression and color space modes are detailed in Table 1, Table 2 and
Table 3, respectively. Table 1 indicates the source packet size for each video mode and color
space mode for compression mode 0. This size is the total number of bytes per source packet,
i.e. type specific information and source packet data. All the source packets of a given stream
are this size.

IEC 2125/08
Figure 9 – Compression mode 0 16 specific information
The VDSPC (Video Data Source Packet Count) field contains a running count of video data
source packets. It is incremented by 1 for every video data source packet created by the
transmitter. When a stream commences the first video data source packet created has a
VDSPC of 0. Since VDSPC is only 8 bits wide the value placed in VDSPC is the lowest 8 bits
of the running count.
The sol (start of line) field is set in the source packet that contains the first pixel of a video
line. There is no requirement that the start of a video line be coincident with the start of an
IEEE-1394 isochronous packet.
The sav (start of active video) field is set in the source packet that contains the first pixel of
the first active video line of each frame (progressive modes) or of each field (interlace modes).
This field can only be set in a source packet that has sol set. There is no requirement that the
start of an active video line be coincident with the start of an IEEE-1394 isochronous packet.
The line number field is the line on which the video data in the source packet resides as
defined by the video specification given in Table 1 of the given video mode. If no line
numbering is defined by the video specification the line number field shall be a sequential
count of the lines in a frame starting with the first line that is transmitted having a line number.

Compression mode 0 16 video data packetization
For transmission of compression mode 0 16 data the video data that is transmitted is the active
horizontal pixels for both the active lines and the lines of the vertical blanking period (unless
they do not exist). The first pixel of a video line shall always be the first pixel in a source
packet and each video line shall always fill an integer number of source packets. The number
of pixels in each source packet is dependent upon the video mode and color space and is
detailed in Table 1. An IEEE-1394 isochronous channel that is used to transmit data
according to this specification shall only transmit a single stream of video per 1394
isochronous channel.
